Magnesium Glycinate 400 mg Supports Sleep, Relaxation & Cardiovascular Health*
LifeSource Vitamins Magnesium Glycinate is a research-driven formula designed for those seeking daily support for relaxation, sleep quality, and muscle & nerve function. This chelated form binds magnesium to glycine — a calming amino acid — to enhance absorption while remaining gentle on digestion. Backed by NIH-indexed human clinical studies and produced in FDA-registered, GMP-certified facilities, this formula delivers clean, proven magnesium support you can trust.*
Research Promise:At LifeSource Vitamins, our commitment is rooted in research and results. Every benefit below is supported by human clinical studies indexed in the National Institutes of Health (NIH) via PubMed, with full texts available in the National Library of Medicine (NLM) PubMed Central (PMC) when available. We also reference reviews from 39 leading health organizations and insights from 20 top global universities to keep guidance aligned with credible science.*
